INR Monitoring For Warfin & Bloodtests

If you are on Warfarin (Blood thinner) for a special medical condition, You are required to do a regular blood test to check its level (INR). You will have lab test form with you to give it to the lab when you are doing it. You will always keep a copy of it to present to the lab. You will have to keep your INR at a specific range, eg 2 to 3 or 2.5 to 3.5, depending on your health condition. If it s too low then the medicine will not give you enough effect and if its too high, it will increase your chances of a significant bleed. Therefore it is important to check it regularly.
